Low temperature operation of a solid-oxide Fe-air rechargeable battery using a La0.9Sr0.1Ga0.8Mg0.2O3 oxide ion conductor

We investigated a catalyst for oxidation of Fe powder using steam and it was applied to a Fe-air rechargeable battery based on the low temperature operating Solid Oxide Fuel Cells technology. Stable charge-discharge cycling over 20 cycles was achieved at 673 K.
